With BTC sooner or later within these days hitting the 10k mark (now around 9-10k) i cant help but wonder if one can buy BTC and still make a profit or should i just hold on to my ethereum and watch the market due to the fact that it can fall back
It's going to be a risky proposition, for sure.
Buying anything in the middle of so much attention is going to be risky, especially with bitcoin price being extremely volatile. I think that anything below $10000 right now is pretty much guaranteed profit you should capitalize on that.
Buying at $9900 with price going to $11k soon is a $1k+ turnaround, pure profit.
